Previous research has shown that applications of chemical stimuli to the epiglottis produced distinct patterns of activity in the lamb superior laryngeal nerve. To determine the response characteristics of second-order neurons, we recorded from single cells in the lamb nucleus of the solitary tract (NST) while stimulating the epiglottis with 0.5 M KCl, NH4Cl, NaCl, LiCl, distilled water, 0.005 ...

Laryngeal schwannomas are uncommon lesions with only few cases reported. Herein we present a further case of a schwannoma of the epiglottis, occurring in a 62-year-old with a clinical history of a cutaneous malignant melanoma and laryngeal glottic keratosis. The schwannoma was incidentally discovered as a small polypoid lesion located on the laryngeal surface of the epiglottis and was removed e...

to recall certain normal processes involved in this function. In the laryngo-pharynx the most important mechanism is the closure of the larynx. This is effected by the apposition and tilting forward of the arytenoids and the apposition of the aryepiglottic folds, while a raising of the larynx brings the arytenoids with their cornicula into contact with the cushion of the epiglottis. The contrac...

In our work we aimed to study the pathomorphological manifestations among structural components of laryngeal mucosa and cartilage in later stages experimental opioid effect. This goal was achieved through use histological techniques visualize cartilage. Histological sections with a thickness 5 -7 mm were made. specimens prepared according conventional methods using dye hematoxylin, eosin, azan ...
